Sure, it might seem to be nothing more than a simple calculator when you hold up your handset in portrait mode, but when you turn it into landscape mode, then all the addition, subtraction, multiplying and division would receive additional mathematical companions, if you will, as it is transformed into a scientific calculator that sports the relevant buttons for sine, cosine, tangent, logarithm and pi.
If you were still to prefer making use of the scientific calculator function in portrait mode, fret not. There is an easy way out, and that would be swiping to the left. By doing so, a panel will slide out that will carry all of the relevant buttons required in order to complete those far more complex computations. The icing on the cake? The Google Calculator will support Android Wear as well.
